By Lori EhdeCor-Tech Manufacturing officially closed its doors Friday, according to owner Jamie Stratton.The announcement comes near the second anniversary of the fatal accident his friend and co-worker Nick Mann.Mann, 26, was killed July 31, 2002, when a tire he was working on exploded in the Cor-Tech shop.Stratton said the business took a hit as a result of the accident, but he said that’s not why it’s closing. "It’s not just the accident," Stratton told the Star Herald Tuesday. "There are a lot of circumstances involved."The business, located on Gabrielson Drive, most recently employed five people, including Stratton and his brother, Corey Stratton, who owns the building and property.Following the accident, Cor-Tech announced it would no longer accept individual repair work and would focus instead on major manufacturing projects.Two employees were laid off at that time.The decision followed an investigation and subsequent fine by the Occupational Safety and Health Administration. Higher insurance costs made it impossible stay in the private repair work, Stratton said at the time.He said the future is uncertain for himself and his employees, and no decisions have been made yet about the building and property. "I want to thank everyone for their support and continued support," he said.Cor-Tech opened nearly 10 years ago for the purpose of repairing farm equipment and custom manufacturing parts for people and businesses.The Strattons have owned it since 1992, and until the accident employed nine people.The shop had a reputation for manufacturing unique equipment for specialized industries. For example, Cor-Tech designed and manufactured the City of Luverne’s trailers that are used to collect residential recyclables.Cor-Tech’s latest major client has been Jennie O, which had Cor-Tech manufacture its loaders and cages for hauling turkeys.
